I'm not sure what you want to achieve, but if you want the page to remember things, you need to start a session. This will remain current until you then logout. Try putting this at very first line on the page.

<?php
session_start();
?>

hi, do i need sessions? i want to continuously add items to the sales table, like in the picture, i've added a single item, but every time i search again for an item, the page reset, at the same time my sales table which is below, items will be gone, do i need another condition to continue adding items below even if i search for another item?? huhuhu,,, :(

Try below code.
Here i have used session to remember previous items.

<? session_start();?>
<title> SALES </title>
<body>
<form action="index.php" method="post">
ENTER ID: <input type="text" name="item" />
<input type="submit" name="submit" value="submit"/>
<input type="submit" name="refresh" value="refresh" meta http-equiv="refresh" />
</form> 



<?php
include("connection.php");

if(isset($_POST['submit'])){
$sel_item = $_POST['item'];
$query  = "SELECT * FROM items where {$sel_item} = id";
$result = mysql_query($query) or die();
echo "<table>";
echo "<tr><th>ID</th> <th>ITEM NAME</th> <th>DESCRIPTION</th> <th>SIZE</th> <th>COLOR</th> <th style='text-align:right'>PRICE</th> <th style='text-align:right'>QUANTITY</th></tr>";

while($row = mysql_fetch_array($result)) {
	
	echo"<tr><td>";
	echo $row['id'];
	echo"</td><td>";
	echo $row['item_name'];
	echo"</td><td>";
	echo $row['description'];
	echo"</td><td>";
	echo $row['size'];
	echo"</td><td>";
	echo $row['color'];
	echo"</td><td style='text-align:right'>";
	echo "P".$row['price'];
	echo"</td><td style='text-align:right'>";
	echo $row['quantity'];
	echo "</td><td>";
		
}
echo "</table>";
}
?>

session_start must be first line of your code.
<?php session_start();
There should be no blank space or line breaks before this function start.
